TT gets checkraised by a Lag that knows I'm tight.

[flytrap]

The game is 5/10 NL at Motorcity Casino in Detroit. There is no cap on the buy-in, with a 300min. I have about 1800, villain has me covered. He is a solid player, although he's somewhat loose, and is prone to checkraising the flop, especially against tight players. His impression of me is that I'm pretty tight. The game is 10 handed. UTG calls, 3 folds, I make it $45 with Black Tens, folds to the Villain in the SB who calls, BB folds, limper calls.

Pot ($150)

They both check, I bet $125, tag raises to $350, UTG folds, I insta-call.
