When the sun, moon, and earth are in alignment (new moon & full moon), the tides are higher. When the sun-earth-moon forms a right triangle (first and last quarters), the tides are weaker because the sun and moon are not working in tandem.
With respect to the tides, it's not correct to say the sun and moon are working against each other when they're algned with the earth in the middle. Rather than working against each other, they're both tugging at the earth, but from opposite directions. Nevertheless, it's true that other things being equal, the highest tides will occur when the moon is between the sun and the earth.

we really have 2 high tides at the same time...
The timing of tidal events is related to the Earth's rotation and the revolution of the moon around the Earth. If the moon was stationary in space, the tidal cycle would be 24 hours long. However, the moon is in motion revolving around the Earth. One revolution takes about 27 days and adds about 50 minutes to the tidal cycle. As a result, the tidal period is 24 hours and 50 minutes in length.
The second factor controlling tides on the Earth's surface is the sun's gravity. The height of the average solar tide is about 50 % the average lunar tide. At certain times during the moon's revolution around the Earth, the direction of its gravitational attraction is aligned with the sun's During these times the two tide producing bodies act together to create the highest and lowest tides of the year. These spring tides occur every 14-15 days during full and new moons
---- or --
Tides are caused by slight difference in gravity between the Earth and the moon and the sun in relationship with locations on the Earths surface. Tides are timed primarely because of the cyclical influence of the earths rotation around the sun and the moon and the fake axis between the earth and moon.
The moon is the factor controlling the timed rhythm and height of tides. The moon produces two tidal bulges somewhere on the Earth through the effects of gravity. The height of these tidal bulges is controlled by the moon's gravity force and the Earth's gravity pulling the water back toward the Earth. At the location on the Earth closest to the moon, water is drawn toward the moon because of the greater strength of gravity. On the opposite side of the Earth, another tidal bulge is produced away from the moon this bulge is caused because it moons gravity is weaker and the moon is on the otherside of the earth..so the water is “:chasing” the moon any given point on the Earth's surface there should be two tidal waves and two low tides.

as far because of fact the moon and not the solar, the area in area because of fact the earth is from the solar, is merely too super to have any gravitational allure, besides the orbit. The moon is plenty closer, and has a smaller pull, yet pulls on the earth rapidly, while the solar pulls on all of the planets. in the process the extreme/low tides, permit me supply an occasion" say you had a magnet, and a tumbler field crammed with iron shillings with a great, think of wood side. placed the magnet on the fringe of the glass field devoid of the timber, and the iron shillings will pass in the direction of it, placed it on the different fringe of the timber, and not something will take place. same ingredient with the moon and tides, as long because of fact the moon is dealing with the water, it pulls on it, yet as quickly because it strikes at the back of the earth's mass, there is all that rock and middle between the two issues, and extreme tide happens on the different fringe of the earth. Ponds, lakes, and different such our bodies of water won't have tides, because of fact, as you stated, there merely isn't sufficient mass to drag on.

When the earth is between the sun and moon their gravitational influence acts against one another. When the moon is on the same side of us as the sun, they team up and pull with greater force working together on our oceans.
