Today I was playing 1/2 nl and I got into 2 situation that were similar but with different cards... The first one I was holding KQo on the button and raised to 6, folds around to bb that has been playing tight and he raised to 10. I think for a bit and called... I flopped the nuts flop came ATJ rainbow BB bets 20 I raised to 45 he shipped it all in for $110 I snap called he showed A4s... turn card was 4 and the river was a 4 as well... How would've you played this hand ?? Did I messed up on something ???

Second situation after doubling up 25 min after that hand. I picked up 7's on the button and flat called a raised to 10 that the lady on mp2 put, big blinds flats as well. The flop came A7T two hearts. bb checks lady bets 20 I raised 45 bb folds she moved all in for another 75 bucks I believed. I went into the tank for about 2 and half minutes and called. flop was a 2 and river another T that gave her 10 full of aces.... After this hand I walked away.... Any advice or tips on this 2 situations ?? I would appreciate it.

Happy holidays!!!
