Spots like these always seem to confuse me. I feel like we have 3 options - shove, bet 1/2stack, or bet tiny. I've always leaned towards shoving more so than betting about 1/2stack b/c I think it gets called more than 1/2 as much of the time. I seem to ignore betting real small in general. This is one of those spots I've never had a great understanding of. Any input is welcomed.
