lizard29 is all-In [790]
D_Maybe is all-In [605]

My case is the following
Lizard is pushing any 2 or at least top 70%, he has been pushing before.
Im getting 3 to 2 for my money.
All the table, except,Lizard is very tight.

If I dont call here Lizard will keep exposing me to more and more -EV desitions. If I call and succeed a bunch of +ev situations arrive since I will be doing some serious pwning to the tightweakies on my right. So to sum it all up : Im doing a -ev desition on the short run to create the possibility of +ev spots later on.

Anyway, am I a huge idiot?
