Human Factors
[I was] positioned 2-3 miles northwest of 3CK at 3;500 FT with intent to over fly field north to south to enter pattern for Runway 26 at 3CK. Second aircraft (Bonanza) northbound and 2 miles south of 3CK made CTAF announcement with intention of over flying field south to north at 3;500 FT. I immediately climbed approximately 400 FT - 500 FT (to 3;900 FT-4;000 FT MSL) to avoid oncoming traffic which a few moments later passed several hundred feet below and slightly to my left (east). I then immediately descended to 2;500 FT and then to 1;900 FT (TPA) and completed a normal landing at 3CK. Bravo airspace (4;000 FT - 10;000 FT) may or may not have been momentarily infringed upon during this evasive climb.
PA28 pilot reported NMAC with a Bonanza in the vicinity of 3CK.
